Objective To explore the value of blink reflex (BR) and brainstem auditory evoked potential (BAEP) in the diagnosis of multiple sclerosis (MS). Methods Totally 20 normal persons and 32 MS patients were examined with BR and BAEP respectively.Results 32 MS patients were divided into two groups according to the abnormalities localized to the brainstem: the symptomatic group and the asymptomatic group. The abnormal rates of BR in two groups were 85.7% and 50.0% respectively. The abnormal rates of BAEP in the two groups were 71.4% and 44.4% respectively. The abnormal rates of BR in Ⅴand Ⅶ cranial nerves were both 21.9%. The abnormal rates of BR,BAEP,BR and BAEP in finding out lesions of brainstem were 65.6%,56.3% and 75.0% respectively.Conclusions Subclinical lesions in brainstem, Ⅴand Ⅶ cranial nerves were demonstrated by BR. The combined abnormal rate of BR and BAEP was higher than either test alone.

With the development of computing and storage techniques,there are a lot of medical records and clinical data stored.It raises the issue of how to mine knowledge from these records and to promote the development of traditional Chinese medicine (TCM).Several challenging research subjects of Chinese clinical medicine data mining and analysis have been introduced in the framework of disease-symptom-syndrome-formulaeffect,and the corresponding developments have also been reported.The significant meaning of the data mining and analysis to Chinese medicine is discussed.Then,the detailed works and recent achievements of seven subjects are given including:① Analysis of symptoms to obtain the optimal symptom subset for one disease or syndrome.② Symptom-syndrome or disease to obtain models for syndrome differentiation.③ Analysis of syndrome.④Analysis of Core formula as well as drug addition and subtraction.⑤ Formula-symptom-effect.⑥ Computerized symptoms.⑦ TCM knowledge engineering.

Objective To explore the MRI features of brain and spinal cord in patients with multiple sclerosis(MS).Methods The data of MRI of 110 patients with clinic definite MS were analyzed retrospectively.Results The lesions on brain MRI were usually seen in the white matter surround the ventricle(55.8%),deep frontal lobe white matter(54.7%),deep parietal lobe white matter(44.2%)and brainstem(25.6%).Basal ganglia(23.3%)and thalamus opticus(11.6%)were also affected.The size of the brain lesions was varied,the appearances were punctiform,mottling,patching,ellipse and so on.The lesions of the spinal cord were usually on the cervical cord(75.0%)and thoracic cord(68.8%).There were string lesions which parallel spinal cord long axial and mottled lesions.The spinal cord lesions existed in both white matter and gray matter.10.0% of the patients had spinal cord atrophy or spinal cord swelling.The signal intensity of lesions was equal T1,long T2 or long T1,long T2,which was related with the clinical course.Conclusion Different size and appearance lesions in the white matter of brain and spinal cord are the main MRI features of MS.

Reversible posterior leukoencephalopathy syndrome (RPLS) is a cliniconeuroradiological entity mainly characterized by the rapidly progressive increase in blood pressure, headache, vomiting, conscious disturbance and seizure. Neuroimaging showed symmetrical reversible white matter edema in bilateral cerebral hemispheres, particularly in posterior brain.Clinical symptoms and neuroimaging changes can be recovered completely with timely and correct treatment. The two major hypotheses about the pathogenesis of RPLS-cerebral vasospasm and cerebrovascular hyperperfusion-have been in dispute. At preseut, most researchers still agree that the latter is the main cause of cerebral edema. This article expounds the new viewpoints of its pathogenesis and the above two major hypotheses in recent years from the characterizations of etiology, pathology and imaging of RPLS.

Objective To investigate the clinical manifestations and possible mechanism of the multiple sclerosis (MS) combined with uveitis Methods Two cases of MS combined with uveitis were clinically observed by electro physiological, brain MRI and oligoclonic band (OB) examinations,the cases were analyzed and subjected to assessment Results Case1, a 56-year-old man had symptoms of one month′s numbness and twenty-day sudden decrease of visual acuity Viusal evoked potential (VEP)showed a postponed latent period of bilateral P100 waves Brain MRI showed multifocal T 2 Wight Image high signs in subcortical white matter of frontal and parietal lobes OB was postive Case 2: a 35-year-old woman, had recurrence of decrease of visual acuity of bilateral both eyes for 12 months and bilateral lower-limbs numbness Latent period of VEP P100 waves and BAEP I-V waves were postponed Brain MRI showed multifocal round-like T 2 Wight Image high signs in white matter of frontal and parietal lobes OB was postive Referring to the essay reported ,MS combined with uveitis was moetly moderate in manifestations Their causes were uncertain It is suggested that MS is not due to auto-antigen but due to S100-? protein derived from star-like cells Conclusion MS combined with uveitis ,unlike other one ,was clinically moderate and the pathological mechanism is unclear It is suggested that autoantigen such as S100-? protein derived from star-like cell results in MS and uveitis, not in MBP

Objective To assess the predicting value of homocysteine ( HCY), low density lipoprotein cholesterin (LDL-C) and carotid intima-media thickness (IMT) for women with coronary artery disease (CAD). Methods To choose 115 patients with CAD and 102 patients of non-CAD;Homocysteine, LDL-C and IMT were assayed respectively;comparison and correlation analysis were performed based on genders. Results The rates for hyperhomocysteinemia and High Lipoproteinaemia in female CAD patients are 59. 6% and 75.0%,respectively,while they are 69. 9% and 78.6% for male CAD patients,which are both remarkably higher than 23.0% ,26.7%, 22. 2% and 23.6% in non-CAD patients ( Ps ＜ 0. 05 ). ROC curve shows that the best diagnostic boundary point is 0.953 mm for female IMT and 1. 021 mm for male IMT. At the boundary point,the sensitivity,specificity,positive predictive value and negative predictive value are 83.7% ,91.4% ,95.7% and 63. 8% in female, much higher than 62.9%, 65.3%, 76.2% and 53.3% in male. Conclusion hyperhomocysteinemia, high lipoproteinaemia are the important risk factors for women with coronary artery disease;IMT might be used as the predictor of CAD, which have more advantages for female than for male patients.

0.05).No significant difference was shown among the four groups for the proportions of brainstem involved(P=0.335).Significant differences were found for the proportions of bilateral hemicerebrum and spinal cord involved(P

Firstly, this article introduced the definition of medical dispute and public remedy. Thereafter, it analyzed the causes of public remedysilence in medical disputes from four perspectives including the self-defect of public remedy, inadequacy of legal construction, lack of trust in public remedy, and the popularity of private remedy. Finally, it pointed out the countermeasures of enhanced legal construction, unimpeded public remedy and striking private remedy to solve the problem of public remedy silence in medical disputes.

Objective To investigate effect of sorafenib on serum hepatoma marker in patients with advanced hepatocellular carcinoma. Methods 101 patients with advanced hepatocellular carcinoma were selected, and divided into two groups.50 cases in control group were treated with routine clinical treatment, and 51 cases in experimental group were treated with sorafenib on the basis of control group.The survival time, adverse reactions, VEGF, CTGF, HIF-1 and OPN levels were compared after the treatment.Results The survival time of experimental group was higher than control group (P<0.05).Compared with control group, the serum levels of VEGF、CTGF,HIF-1, OPN,AFP, CEA, and CA199 in experiment group were lower (P<0.05,P <0.01).There were no significant differences of total adverse reactions between experimental group and control group. Conclusion Sorafenib can effectively prolong survival time of patients with advanced hepatocellular carcinoma, reduce serum VEGF, CTGF, HIF-1 alpha and OPN levels.

Chronic low back pain is a common type of pain which is related to the dysfunction of low back muscles. In recent years, the pressure biofeedback has been widely used for the assessment and treatment of chronic low back pain. This paper reviewed the reliability and validity of pressure biofeedback unit in the evaluation of lumbar and abdominal muscles activity, as well as its application on the rehabil-itation of chronic low back pain, which mainly related to the assessment and treatment of lumbar muscle activity and lumbar spine stability.
